The Sex Offender registry in itself is really fucking dumb. The way society looks at it is even worse. Lets just say, John Doe rapes a woman. He rapes her and then leaves her house. He doesn't kill her, or beat her up. Lets even say that she was drunk or unconscious. This guys life is over. He will go to jail, and basically have no chance of getting work ever again. His family will be known as the family that has a rapist in it.
Even murderers and man slaughterers can get jobs after doing that. This guy , 19 year old who slept with a 14 year old who lied. His life is over. Unless he is an utter genius, he will never get a job until his 40s at least. His family will be known as the rapist family. Half of them have probably already disowned him.
Meanwhile if it was 3rd degree homicide it wouldn't even be brought up - and rightly so. No one should have their entire life be ruined because a child ran in front of their car.
